Title: Transfer process of conductive magnetic toner image
Inventor: TEJIMA AKITOMO
IPC: G03G13/16
Filed: 1978-02-21
Abstract: PURPOSE: To increase the transfer efficiency of conductive magnetic toner and reduce the running cost, by using an ordinary paper having printed on the entire surface as the transfer paper.  
     CONSTITUTION: An optical image is radiated by an exposure device 4, and an electrostatic latent image 11 is formed on the surface of a photoconductor 2 on a drum 1. This electrostatic latent image 11 is developed in a conductive magnetic toner developing bath 5, and a negatively charged toner image 12 is formed. Then, applying a positive voltage to a conductive rubber roller 7, the negatively charged toner image 12 is transferred on the transfer paper 6. At this time, the printing ink printed on the transfer paper 6 serves as an insulator, so that the toner image 12 may be easily transferred onto the transfer paper 6 without leaking the charge of the toner 12. Thus, the transfer efficiency is increased.

Title: Travel controller for electric motor vehicle
Inventor: YOSHIDA SUSUMU
IPC: H02P7/29
Filed: 1982-02-08
Abstract: PURPOSE:To enhance the operating efficiency of a travel controller without losing climbing capacity or maximum towing force by controlling the acceleration by providing high and low set values in the overcurrent limiting function of a travel motor which is controlled through a chopper from a DC power source. CONSTITUTION:A motor current detection signal (i) is applied to one input terminals of operational amplifiers OP1, OP2 as comparators. The charging voltage of a condenser C1 is applied to the other input terminal of the amplifier OP1. The C1 is charged at the reference voltage Vref when the motor current is lower than the limited value, and charged at the value larger than the voltage Vref with partial voltage by resistors R1, R2 of the voltage of the logic level 1 of the amplifier OP2. The voltage Vref is applied to the other input of the amplifier OP2. The output of the amplifier OP1 is connected through a diode D1 to the terminal (g) which produces a conduction ratio throttling signal of a chopper. In this manner, when force is necessary such as in case of climbing, the set value of the overcurrent limiting function of the motor can be automatically increased.

Title: Bonding sheet for semiconductor device and apparatus for manufacturing bonding sheet
Inventor: FURUTA TSUNEHISA
IPC: H01L21/60
Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To remove air between a TCP tape and a thin plate and to thereby prevent bubbles from remaining therebetween, by providing an adhesive on a bonding surface of a semiconductor device, the adhesive having grooves allowing air to pass therethrough formed so as to reach edges of the thin plate. SOLUTION: Grooves 21a of an adhesive 21 extend to reach edges of a thin plate 32. Since a plurality of grooves 21a are formed in an adhesive sheet 31, air can be driven out of the grooves 21a during pressure bonding. As a result, remaining air between a TCP tape 41 and the plate 32 can be removed. Further, even when bubbles are produced by entrapping air into surfaces other than the grooves 21a of the sheet 31, the presence of the grooves 21a in the sheet 31 allow the remaining air between the tape 41 and the adhesive 21 to be removed. The width and number of the grooves 21a in the sheet 31 can be varied, and thus the size of bubbles can be adjusted. As a result, the breakage of the tape 41 can be prevented, and thus the occurrence of defects can be prevented.

Water from a water tank 6 is fed into the hollow parts of a hollow element 5 through water inlet ports 3 via solenoid valves 2, and is held in those parts. Dry air is fed into the spaces in the hollow element 5 from the direction (c). The water held in the hollow parts is heated and is turned into steam, which permeates through porous sheet of element 5 made of hydrophobic polymer, evaporates and is contained in the air, and the humidified air with steam is discharged from the element 5 to the direction (d). The evaporated amount of water is replenished from the tank 6 at any time. The capacity of a humidifier can be controlled in a wide range by dividing hollow parts into a plurality of passages and by controlling the rate of feed water.
